Amazon has announced (at least to two different sites) that it will soon accept used music CDs, in exchange for Amazon gift cards. As with Amazon's Trade-In program for DVDs, textbooks, electronics, and other items, you tell Amazon what you're sending on their trade-in site, ship it yourself, and then receive a gift credit, generally within 6-10 business days. CDs aren't showing up on Amazon's trade-in list right now, but are expected to appear soon. That adds to Amazon's stature as one of the best places to trade in used stuff.
